How to render html within rich?

[shawnkoh]

Is it possible to render HTML within rich itself?
Use case: rendering the difference between two strings.

An easy way to do this would be to use difflib but it generates a string of html.
Curious if it's possible to render that html within rich itself without having to parse it.

here's a very simple attempt
dependencies:

• parsy
• PyFunctional

def print(before, after):
    from rich.console import Console, Group
    from rich.panel import Panel
    from rich.text import Text
    from more_itertools import peekable
    import parsy

    console = Console()
    diff = unified_diff(
        before.split("\n"),
        after.split("\n"),
        fromfile="before",
        tofile="after",
    )

    diff = peekable(diff)
    if not diff:
        return

    any_chars = parsy.any_char.at_least(1).concat()
    pp = (
        (
            parsy.peek(parsy.string("@@"))
            >> any_chars.map(lambda x: Text(text=x, style="bold magenta"))
        )
        | (
            parsy.string("-")
            >> any_chars.map(lambda x: Text(text=x, style="bold red"))
        )
        | (
            parsy.string("+")
            >> any_chars.map(lambda x: Text(text=x, style="bold green"))
        )
        | (parsy.string(" ") >> parsy.any_char.at_least(1).concat().map(Text))
        | (
            parsy.string("?")
            >> any_chars.map(lambda x: Text(text=x, style="bold magenta"))
        )
        | (any_chars.map(Text))
    )

    diffs = seq(diff).drop(2).map(pp.parse)

    console.print(
        Panel(
            Group(*diffs),
        )
    )
